A text at 3am is a note for the morning. A phone that rings is a response. OpenAlarm lets you text first and call in a later level, or call first at night. Your call, literally. docs.openalarm.io/guides/contacts-policies/ #HomeSecurity #SmartHome #HomeAssistant #SMS #SelfHosted #DIY #HomeAutomation

Contacts & Policies

The people OpenAlarm can reach and the order it reaches them in - consent-first contacts and escalation policies.

Bilge pump running too long is a boat problem you want to hear about on shore. If it can call a URL, it can trip OpenAlarm, which rings the people you chose until one answers. docs.openalarm.io/api/ #Boating #Boat #IoT #DIY #HomeAssistant #SmartHome #SelfHosted #API #Maker

Your people get texts, voice calls and email, in the order you set, until someone acknowledges. A DIY notification can't do that on its own; OpenAlarm does it for the alarm you already run. openalarm.io #HomeAssistant #SmartHome #SelfHosted #HomeSecurity #DIY #IoT #HomeAutomation #SMS

OpenAlarm | Alarm alerting for the security system you already own

OpenAlarm is an alarm alerting platform for the security system you already own: when Home Assistant, UniFi Protect or anything that can call a URL trips, the people you trust get a text, a call and an email until someone answers.

OpenAlarm @openalarm.io · 10/10/2026

I made every API call a GET with no body so a dumb webhook could fire it. That's how your own alarm trips OpenAlarm. Some people find that odd for a trigger. Would a POST have felt more correct to you? #BuildInPublic #API #Webhooks #SelfHosted #HomeLab #IndieHackers #DIY #IoT

OpenAlarm @openalarm.io · 10/10/2026

curl one URL and your test incident works through the whole chain: who, in what order, how far apart. That's the OpenAlarm API demo, and it's the same URL your own alarm will call. docs.openalarm.io/guides/quickstart/ #SelfHosted #HomeLab #API #DIY #HomeAssistant #IoT #Sysadmin #HomeAutomation

Incidents end exactly three ways in OpenAlarm: you clear it, a disarm clears it if you set it that way, or it expires 24 hours after escalation ends. Nothing lingers by accident. docs.openalarm.io/guides/incidents/ #HomeSecurity #SmartHome #HomeAssistant

One account covers the house, the cabin and the rental. Ten locations on every OpenAlarm plan, each with its own alarms and dashboard, each alerting the people you chose. openalarm.io/pricing/ #HomeLab #SelfHosted #HomeAssistant #SmartHome #HomeSecurity #Landlord #Rental #DIY #IoT

Pricing | OpenAlarm

Two plans, no contract, all prices USD. Both do everything OpenAlarm does, escalation included. Free alerts your people by email, forever. Pro is $6.99/mo or $69.99/yr and adds SMS and voice calls. Every new account starts on Pro for 14 days, no card needed.

Bluesky, by far, has been the most engaging.

OpenAlarm @openalarm.io · 06/10/2026

I would love for you to give us a try! We offer custom escalation policies that the user builds themselves. Up to 5 levels, any number of available contacts per level with delays and repeats. 24 hours only applies if the incident isn't otherwise cleared or acknowledged.

OpenAlarm @openalarm.io · 06/10/2026

I built this alone, and one thing I still second-guess: is a 24 hour auto-expiry on unanswered incidents too long, too short, or about right? Genuinely unsure. This is OpenAlarm, which calls your people when your own alarm goes off. #BuildInPublic #IndieHackers #SaaS #HomeSecurity #HomeAssistant

Scope an API key to a single alarm and put it in your UniFi console. Even fully leaked, that OpenAlarm key can fire exactly one thing and change nothing else. docs.openalarm.io/guides/authentication/ #UniFi #UniFiProtect #HomeLab #CyberSecurity #InfoSec #SelfHosted #API #HomeSecurity #Networking

An alarm URL without its key can't fire anything. OpenAlarm keeps the key in a header, never in the URL, so a scanned, logged or prefetched link is inert. Your alarm stays yours to trip. docs.openalarm.io/guides/authentication/ #HomeLab #SelfHosted #CyberSecurity #InfoSec #API #HomeAssistant

Originally OpenAlarm had the predefined 4 modes and the ability to create additional custom, named modes. We decided that was entirely unnecessary. We think the 4 we have now is more than enough for our users, by far 🙂

OpenAlarm @openalarm.io · 01/10/2026

Design note: the mode list is Home, Away, Night and Vacation, and it's closed. Each is a state Home Assistant already has, so nothing in OpenAlarm collapses into a custom state HomeKit can't show. docs.openalarm.io/guides/arming/ #BuildInPublic #HomeKit #HomeAssistant #Apple #SmartHome #HomeSecurity

Your alarm panel card in Home Assistant can arm, disarm and trigger OpenAlarm like any other panel, and an open incident shows as triggered until it clears. Same card, your people get called. docs.openalarm.io/guides/home-assistant/ #HomeAssistant #HACS #SmartHome #HomeAutomation #SelfHosted #DIY
